: encompasses several species of free-living ameba encountered commonly throughout the environment. Unfortunately, these species of ameba can cause opportunistic infections that result in keratitis, granulomatous amebic encephalitis, and occasionally systemic infection.: This review discusses relevant literature found through PubMed and Google scholar published as of January 2021. The review summarizes current common keratitis treatments, drug discovery methodologies available for screening potential anti- compounds, and the anti- activity of various azole antifungal agents.: While several biguanide and diamidine antimicrobial agents are available to clinicians to effectively treat keratitis, no singular treatment can effectively treat every keratitis case.Efforts to identify new anti-Acanthamoeba agents include trophozoite cell viability assays, which are amenable to high-throughput screening. Cysticidal assays remain largely manual and would benefit from further automation development. Additionally, the existing literature on the effectiveness of various azole antifungal agents for treating keratitis is incomplete or contradictory, suggesting the need for a systematic review of all azoles against different pathogenic strains.

Adult Kerion Caused by Trichophyton tonsurans.

Mycopathologia

January 2025

Department of Dermatology, Wuhan No.1 Hospital, Wuhan, Hubei, China.

Adult tinea capitis, especially kerion, caused by Trichophyton tonsurans is relatively rare in China. Here, we report a case caused by the agent in an old woman with normal immune function. Fungal microscopic examination and culture were positive.

Chronic granulomatous disease is the inborn error of immunity with the highest frequency of invasive aspergillosis. In this context, invasive aspergillosis is frequent in adolescence, with rare cases before one year of age. We present a case of chronic granulomatous disease and invasive aspergillosis in a four-month-old infant.

Background: The epidemiology of vulvovaginal candidiasis (VVC) in Greece remains poorly reported and outdated.

Objectives: We therefore conducted a 2-year retrospective survey to assess the epidemiological aspects of the infection among symptomatic Greek patients.

Patients/methods: High vaginal swab samples were collected from adult women with clinically suspected VVC attending a private diagnostic laboratory in Athens.

The antifungal drugs of the echinocandin family show high efficacy against Aspergillus fumigatus. However, their paradoxical effect, which restores fungal growth at high drug concentrations, and the emergence of resistant strains necessitate improvements. We identified 13 fluoroquinolone compounds from a chemical library containing 10,000 compounds that potentiate the antifungal activity of caspofungin.

Background: Early antifungal initiation in invasive aspergillosis (IA) is recommended. Changing antifungals occurs for a myriad of reasons but associated costs are unclear.

Methods: US claims data for adults admitted for IA were identified from 10/1/2015 to 11/30/2022.
